Location

Tochōmae Station (都庁前駅, Tochōmae-eki; Metropolitan Government Station) is a subway station on the Toei Ōedo Line in Shinjuku, Tokyo, Japan, operated by the Tokyo subway operator Toei Subway. The name of this station suggests its location in front of the Tokyo Metropolitan Government Building, and it is the nearest station to that complex.

Unusually, the station is both a terminus and a through station on the same line. Inbound trains pass through the station, travel south to complete a counterclockwise loop around central Tokyo, and terminate at Tochōmae. Outbound trains do the opposite, departing northbound from Tochōmae, traveling clockwise and eventually passing through the station again on the way out. Consequently, passengers may need to transfer from the Ōedo line to the Ōedo line at this station.

Lines

Tochōmae Station is served by the Toei Ōedo Line, and is numbered "E-28".

Station layout

The station consists of two island platforms on the 3rd basement ("3BF") level, serving four tracks. There are seven exits from the station, numbered A1 to A7.

History

The station began construction on August 28, 1990, and opened on December 19, 1997.

The temporary name before its opening was "Nishi-Shinjuku". The name "Nishi-Shinjuku" is currently used as the name of a station on the Marunouchi Line, and is also part of the name of a station on the Oedo Line called "Nishi-Shinjuku-Go-Chome".

The station was constructed using the cut-and-cover method, with a three-level underground structure, a construction length of 443 m, an average excavation width of 32.7 m (20.2 m - 36.4 m), an average excavation depth of 21.8 m (20.6 m - 28.7 m), a road surface covering of 14,500m2, and an excavated soil volume of 284,000m3, making it a large-scale project.

The siding section near Hikarigaoka Station was constructed at the same time as the shield excavation between Tochomae Station and Nishi-Shinjuku 5-Chome, which is a separate construction area from the station excavation work, and 123 m of the siding was constructed using a shield machine.
